WILLIAM H. HAMAN, (DEUEASED,) OF PHlLADELPEllA, MAGDALENA HAMAN, EXEOUTRIX.

PENNSYLVANIA ROCKING-CHAIR.

SPEGIFICATIQN forming part of Letters Patent No. 252,031, dated January .10, 1852,

Application filed August 3!, 1881.

Pennsylvania, haveinvented a newand useful Improvement. in Rocking-Chairs, which improvement is fully set fozth in the following specification and accompanying drawings, in

. which- Figure l is avertical section of a portion of the rocking-chair embodying my invention. Fig. 2 is a horizontal section in line ac 00, Fig. 1. Fig. 3 is a vertical section of a portion in line y 3 Fig.1, looking to the front of the chair. Fig.4 is a vertical section of a portion in line 2 2, Fig. 1, lookingto the rear of the chair. p i

Similar letters of reference indicate corresponding parts in the several figures.

My invention relates to improvements in spring rocking-chairs; and it consists in rigidly connecting the springs to rigid arms which extend longitudinally backward from the ends of the springs, so that long springs may be employed and gentle motions produced, said rigid arms having sockets which receive the supporting pins or studs and provide firm and reliable connections for said arms and the rocking portion of the chair.

It also consists of the sockets which are attached to or formed with the springs and fitted on the supporting pins or studs, provided with means for lubricating the places of hearing of said pins in the sockets.

Referring to the drawings, A represents the stationary base, and A the rocking portion of the chair placed thereon.

B represents arms, which are secured to the inner sides of the rockers a, and project downwardly along theinner sides of the base A, and serve to preventlateral motions of the portion A without interfering with the proper rocking thereof. The lower end of each arm is formed into or provided with a hook, G, which is adapted to come in contactwith a pin, screw, or stud projecting inwardly from the sides of the base and limit the rearward rocking motion of the chair.

Cast with or secured to each arm B, below the upper end thereof, is a hook, D, theouter (No model.)

the socket E of one end of an arm, F, whose other end is connected to the spring G of the chair. The springs G extend in the longitudinaldireetion of the chair, and are firmed in the presentcase of flat strips of suitable metal, their rear ends being connected to brackets H,

limb whereof is vertical, and has fitted .on it' which are screwed or otherwise secured to the the arms F, as has been stated, and it will benoticed that said arms also extend in the longitudinal direction of the. chair and return or project backward from said forward ends of the springs.

When the chair is rocked motion is communicated to the arms F, and consequently to the springs, which rise and fall, and their power is exerted for purposes usual in such cases.

By the employment of the arms F, I am enabled to use long springs, which work easily and without abruptness, are not liable to break, and obviatethe employmentof heavy and powerful springs, the construction also admitting of employing the arms F, usually of cast metal, as the hearings on the hooks D and connections of the arms B and springs G, said bearings and connections being strong and durable.

Rising from the arms F, above the sockets E, are cups J, each of which has in its base a duct, 1), which communicates with the socket, the Width of the duct being insutficient to allow the protrusion of the upper endof the hook D. The cups J receive a suitable lubricant, which is directed through the ducts b to the sockets E, and consequently lubricates the hooks D, so that the motions of the books on the sockets, and vice versa, are eased and accomplished without noise. 7

The hooks D may be attached to the rockers a independent of the hooks U, the latter being well known and not the subject of the present improvement.

Having thus described my invention, what I claim as uew,and desire to secure by Letters Patent, is-

1. The base and rocking portions A A ofthe chair, in combination with the springs G and rigid or inelastic arms F, the latter being connected to the ends of the springs and returned in thelongitudinaldirection thereofiand formed with sockets E, which are sustained on the studs D of one portion of the chair, substantially as and for the purpose set forth.

2. The base and rocking portions of the-chair and the connected springs,in combination with the arms F, having cups J, and the supports D, said cups communicating with the sockets 10- of the arms F, and the supports D entering said sockets, substantially as and for the purpose set forth.
